METAL-SHEARING MACHINE.

Specification of Letters Patent.

Patented May 23, 1911.

Application filed October 19, 1910. Serial No. 587,945.

To all whom 'it may concern:

Be it known that I, KARL lVAoH'rnR, a subject of the King of Wiirtemberg, residing at lVeingarten, Kingdom of Wiirtemberg, GermanEmpire, have invented certain new and useful Improvements inMetal-Shearing Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in metalshears.

The invention has for its object the provision of simple and improvedmeans for supporting angle irons and T-irons in p0sition to be operatedupon by the shears.

A further object is to provide means for adjusting the support to permitright or left bevel cuts at an angle less than 45.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawings :Figure 1 is a front View of figured ironshears embodying my improvements, the parts being adjusted for arectangular cutting of figured iron. Fig. 2 is a detail illustrating theparts in position for a left bevel or miter cut. Fig. 8 is a sectionthrough Fig. 2 on the line 33. Fig. 4 shows a back-View of the figurediron shears with the angle-iron put in for a left miter cut, the supportbeing in the rear. Fig. 5 is a front view of the shears, the same asFig. 1, with the angle iron put in for a right miter cut. Fig. 6 is adetail front view illustrating a slightly different form of constructionin the same position as Fig. 1. Fig. 7 is an end view of Fig. 6. Fig. 8shows the support according to Fig. 6, adjusted for a left miter cut.Fig. 9 is an end view of Fig. 8.

Referring to the drawings A designates my improved metal shears as anentirety the same comprising a base B and a rotary cutting member B.Secured to one side of the shears A is an adjustable member a providedwith a laterally extended tongue 6 on which is slidably mounted acarrier 0 provided with beveled ends. Said carrier is locked in itsadjusted positions by means of a plug-bolt (Z carried thereby andadapted to engage any one of the recesses e f or g in tongue 5. Asillustrated in Figs. 1 to 5 .the opening in the carrier 0 for tongue 5is nearer one end of the said carrier than the other, whereby saidcarrier serves as an abutment member and is provided with a longprojection c and a short projection 0 either of which may be placed inoperative position by simply reversing said abutment member.

An opening D is provided in the shears to receive the metal 71. to becut, said metal being supported by the edges of said carrier or openingand said abutment member 0.

In the position shown in Fig. 1 the abutment member 0 is in itsmedium-position, and the plug bolt (Z has entered the middle hole 6 ofthe guide rail 5. The longer end 0 of the tongue is pointing upward. Inthis position the tongue serves only as a down holder and an abutment orsupport for the rectangular cutting of angle and T-irons. If now theabutment member a is reversed so that its shorter end points upward, andthen adjusted to the position where plug bolt (Z engages the left hole fof the guiderail 6, it cooperates with opening D to support metal h inposition to provide a bevel cut at an angle of less than 45 on the leftside. The shears can likewise be used after locking the abutment memberC at the right hole 9 of the guide-rail b for beveling angleirons on theright side at an angle of less than 45. Each of the projections c c hasbeveled side and front faces, whereby the abutment is produced.

In the form of construction illustrated in Figs 69 the abutment memberis not moved from the guide rail 6, but is here provided with a suitableinsert piece Is. Said insert piece 70 is reversible and provided withtwo parts k, 70 of different lengths either of which can be inserted inthe carrier 0*. In the adjustment according to Figs. 6 and 7 the shorterend k of the piece is is fixed in the carrier 0 and the long end k is atthe top so that the down-holder is exactly in the position shown in Fig.1 for holding down angle and T-irons when they are cut rectangularly. Ifnow the tongue 0 is shifted and the piece is reversed (Fig. 8) thisadjustment serves exactly the same purpose as Fig. 2, namely as anabutment for cutting angle-irons under an angle of 45.

I claim as my invention 1. The combination with metal cutting shears, ofan adjustable member provided with a lateral tongue, a reversibleabutment member, and means for adjustably supporting said abutmentmember on said tongue, said abutment member being provided withabutments of different lengths.

2. The combination with metal cutting shears, of an adjustable memberprovided with a lateral tongue, a reversible abutment member, and meansfor adjustably supporting said abutment member on said tongue, saidabutment member being provided with abutments of diiierent lengths, saidabutments being each provided with beveled side and front faces.

8. The combination with metal cutting shears, of an adjustable memberprovided with a lateral tongue, a reversible abutment member, and meansfor adjustably supporting said abutment member on said tongue,

said abutment member being provided with abutments of difierent lengths,and means for locking said abutment member in any ad justed position.

4. The combination with metal cutting shears, of an adjustable memberprovided with a lateral tongue, a carrier adjustably mounted on saidtongue, and a reversible abutment member removably secured in saidcarrier and having abutments of difierent lengths.

In testimony whereof, I affix my signature in the presence of twowitnesses.
